Django Login Required Middleware does not redirect

I'm super new to Django and I have created a middleware that should direct my users to the index page with login view when trying to access the pages that are supposed to work only for logged users. Even though I don't get any error in my terminal, it does not work. When I type http://127.0.0.1:8000/profile/ in my browser, I'm still able to see it. Instead of that, I would like to direct my users to the login page.

movie_project/middleware.py

from django.http import HttpResponseRedirect
from django.conf import settings
from re import compile

EXEMPT_URLS = [compile(settings.LOGIN_URL.lstrip('/'))]
if hasattr(settings, 'LOGIN_EXEMPT_URLS'):
    EXEMPT_URLS += [compile(expr) for expr in settings.LOGIN_EXEMPT_URLS]

class LoginRequiredMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        return self.get_response(request)

    def process_request(self, request):
        assert hasattr(request, 'user')
        if not request.user.is_authenticated():
            path = request.path_info.lstrip('/')
            if not any(m.match(path) for m in EXEMPT_URLS):
                return HttpResponseRedirect(settings.LOGIN_URL)

Anyone knows where can be a problem? Thank you so much for any help!

Solution

Your login required middleware does not appear to be doing anything outside of the normal. Is there a reason you have not simply used the login_required decorator on some of your views?

This decorator can be added to any (class based or function based) view where authentication is required. For example

from django.contrib.auth.decorators import login_required

@login_required
def movies_list(request):
    ...

This will then automatically render the view for all users who are logged in and otherwise redirect the user to the LOGIN_URL if not authenticated.

Whilst you can run your own middleware for such auth, I would strongly use the battle-tested options within the Django framework.

In the case of your comment above:

When I type http://127.0.0.1:8000/profile/ in my browser, I'm still able to see it. Instead of that, I would like to direct my users to the login page.

On your profile view function or class base method simply add @login_required with the appropriate import statement (from django.contrib.auth.decorators import login_required).
